PACKIN G OR SHIPPING CARTON.

Application flled January 21, 1926. Serial No. 82,729.

My invention relates to packing or ship ping cartons and more particularly to one of the knockdown type, in that it may be shipped to the user and stored in collapsed condition and opened or set uplwhen it is to be used, thereby effecting economy of space in both shipping and storing;

Cartons or" this kind, while usually 'constructed of light, corrugated strawboard, single or double lined, are of sufficient strength for safe shipment of articles of substantial weight and have come into quite general use as shipping containers for articles ol various shapes and characteristics. Occasionally, it is desired to employ such cartons in shipment of heavy articles in the same carton with articles of a more fragile nature which might be defaced or damaged by contact with the heavier articles or to separate contents of the carton. for other reasons.

Partitioning of the carton'along perpendicular lines often results in a Waste of space, as, for illustration, should such a carton be employed in the shipment of a portable electric heater, consisting of a cast iron base anda relatively large and fragile reflector, with its guard and heating unit, where packing of the parts is not sufiicient to insure against damage to the bulkier but more fragile parts as a result of shiftingof the smaller but heavier base during shipmeat, and perpendicular partitioning of the carton would carton because of the waste of space in the compartment containing the smaller but heavier member.

It is the object of my invention to provide a col-ton of the general type mentioned, wherein the partition may be so arranged as to effect a substantial saving in packing space, and so braced as to prevent its displacement and slippage of the heavier partitioned contents into damaging contact with the more fragile contents.

In accomplishing this object I have provided the improved details of structure hereinatter described and illustrated in the accompanying drawings wherein:

Fig. l is a perspective view of a ship ing carton and a partition of my improved design, adapted for application to the carton, a part of the carton being broken away to show a small, heavy article which it is desired to partition off in the container.

require an excessively large Fig. 2 is a similar view of the same but with the partition in place, illustrating the economy of space resulting from the use of my improvement.

Fig. 3 is a diagonal section of the carton and partition.

ig. 4 is a reduced plan View of a partition blank. i

Fig. 5 is a partition. I Referring more in detail to the draw- 1ngs:-

l designates the carton, which may be constructed of the usual material and in the usual way, here shown to be square, with a relatively small, heavy article 2 located in one corner and the top side and end flaps 3 and 4 open to receive the partition and the balance of a shipment.

The partition, constructed according to my invention, comprises a sheet of lined strawboard corresponding, as to material, with that of which the carton is composed and scored along lines 5, 6 and 7 to form a triangular wall member 8, the sides 5 and 6 of which are equal and the base of a length perspective view of a formed to adapt the partition to the particular size and shape of. the carton with which the partition is to be employed. For a carton square in cross section the sides vof the wall are of slightly greater length than the width of the sides of the carton and the base equal in length to the transverse diagonal of the carton, for the reasons hereinafter made apparent.

Extending from the score lines 5 and 6 are legs 9 and 10, having square corners at their free ends and extending from the score line 7 is a frusto-pyramidal lip 11, the sides of which extend member at an angle to adapt them to fit snugly against the sides of the carton when the partition is formed and inserted into the carton; the length of the legs 9 and 10 being such that they terminate slightly within the carton under such assembled condition.

Assuming the carton and partition blank to be constructed as described, consideration having been had to the size and nature of the articles to be packed in the carton, an article, such as a casting 2 is positioned in one corner of the carton and the partition formed as shown in Figs. 1, 2, 3 and 5 and inserted into the carton until the lip 11 has flat on the from the base of the wall parts,

bottom and the wall member 8 presses against the article 2 or the packing (not shown) which is located around it, and the edges of the wall member engaged with the sides ot the carton. When thewall member and lip are in these positions the legs lie flat against the sides of the carton, with these short edges in contact at the angle of the carton and their free ends slightly within the carton an d parallel with the upper edges of the sides thereof against which the legs lie.

The remainder of the shipment may then be packed in the space divided oft by the partition wall 8 and the flaps 3 and l sealed in the usual manner.

IVith the partition constructed as described, the legs, being of substantially the interior width of tliecarton, brace against the sides of the carton against which their edges lie and the side edges of the lip 11 brace against the sides of the carton opposite the partition wall, to prevent slippage of the partition laterally; the tree ends of the legs engaging the flaps 3 and i to prevent longitudinal slippage. Thus it is apparent that the compartments of the carton are definitely separated and that slippage oi the heavier portion of the contents is resisted by the braced partition wall.

It is also apparent that with the arrangement describeth partitioning of the carton is e'ilccted without loss or space, as the partibe dimensioned to limit the chant tion may her for the smaller article to a size and capacity only suliicient to house the article.

What I claim and desire to secure by Letters Patent is 1. In a carton, a partition comprising a triangular wall member arranged at an incline in one corner of the carton, with its side edges in contact with two adjacent side walls or the carton and its base edge eX- tended diagonally between other corners of the carton, said base edge having a part for extension toward the other corner of said carton.

triangular wall 2. In a carton, a artition comprising a triangular wall mem er' arranged at an incline in'one corner of the carton with its edge in contact with two adjacent sides of an end of the carton, and an extension on the base of the wall member engageable with the other two sides of the carton.

3. In acarton a partition comprising a member arranged at an in cline in one corner of the carton with its side edges in contact with adjacent side walls of the carton and its base edge in contact with one end of said carton, and having an extension at said base for engaging side Walls of said carton.

a. In a carton, a partition comprising a triangular wall member arranged at an incline in one corner or the carton with its edges in contact with two adjacent sides and an end of the carton, and an extension on the base of the wall member engageable with the other two sides of the carton and having face contact with said end thereof.

5. In a carton, a partition comprising a triangular wall member arranged at an incline in one corner of the carton and having legs on its side edges in face contact with adjacent side Walls of the carton.

6. In a carton, a partition comprising a triangular wall member arranged at an incline in one corner of the carton and having legs on its side edges in 'face contact with adjacent side Walls of the carton and a lip on its base edge in face contact with the adjacent end of said member.

7. In a carton, a partition comprising a triangular wall member having edge contact with an end and two adjacent sides 01 the carton, legs on the side edges oi? the wall memberhaving face contact with said sides of the carton, and a lip on the base edge or the wall member having race contact with said end of the carton and edge contact with the other two sides thereof.

In testimony whereof I afiix my signature.
